MACHINE FOR MAKING CELLULOID BUTTONS.

county of Bronx, city'and State of New York, have inventedcertain newand useful I Improvements in Machines for Making Celspecification. 7

My invention relates to a semi-automatic machine for making buttonshaving a celluloid top, and in particular to buttons made of a celluloidtop, acardboard stiffener and.

- a metallic :base.

.7 Buttons of this .kind are well known, and have been extensively used,I and they are usually made by. shaping the flat circular celluloidblank by means of heatand pressure to the required form, and theninserting a cardboard stiffener and attaching a metallic top.

' Celluloid of different grades and different 7 kinds of finish requiresdifierent degrees of heat in orderto shape it properly, as well asdifferent periods of application of "the heat. ln addition, thecelluloid is coated 'with apaint of some kind to color it, and thedifferent qualities of paints also require different treatment.

- My'i-nvention relatesto a semi-automatic machine which shall permit arapid and easy manufacture of these, buttons, while the op erator canreadily observe the process of manufactureand suitably regulate theconditions under which the buttons are made. Other objects of myinvention'will be pointed out in the. following description and drawingswhich illustrate a preferred emmechanism for moving these dies. Fi 8 isav ew sim lar to Fig. 7 showing bodiment, thereof. 1 Figure 1 is a; frontview of my machine. Fig. 2 is a side view thereof. 1 Figs. 3, 4, 5 and 6are rear viewsof the machine showing the dies in various positionsj Fig.7 is a central vertical section through the dies, and, partially showsthe Specifioation of Letters Patent.

position by means of the dog 14:, which is pivoted at 16 to'the stud 17,and as is shown 111 Fig. 1, has a notch 15 which is adapted to fitaround the top of the die 18.

At the upper'part of the machine, a head 1 is moved up and down byanypsuitable means, such as a lever operated by the feet ofthe operator,or any other suitable me chanical movement which is not illustrated V inthe drawings, because. such mechanical movements are in themselves oldand form no part of my invention, and are readily within thecomprehension of any person skilled in theart. I

The head 1 has a circular recess therein, into which a rod 9 fits and'issecured by means of the set screw 8, asshown in Fig. 2. The rod 9 ismoved up anddown in front of the guide-piece 2, as shown in Fig.2. Itcarries the cross head 10 which is immovably therewith. The cross-headlOhas the slide 11 connected thereto. This slide 11 moves up and down withthe cross-head 10, and may also have a sliding, horizontal movement atright angles imparted thereto by any suitable means.

The slide 11, as is shown most clearlyin Figs. 7 and-'8, has a sleeve4:4: secured thereto by means of the bolt 20. To" this sleeve 44, whichis internally threaded, an annular-die 19 is secured.

. secured thereto, and may be made integral This die l9 has, a plunger40 having a recess 50,- slidably mounted therein.- The plunger 40 has apin 41' secured thereto, and the crossrhead 10 is suitably recessed asshown in Fig. 7, so that the pin 41 can be moved to and fro. The plunger40 fits sufliciently tightly into the interior of the die 19 to be heldby friction. The crosshead 10 has a bevel surface 42, as shown in Figs.7 and8,

so that, when the slide 11 is moved a sufficient distance to the left;this-bevel surface 42 forces the pin 41 and the plunger 40 downwardlyasis shown in Fig. 7.

At the right of the die 19, a cylindricalthreaded head. Tothis die 46a'ring-shaped die 12-issecured by-means of a spiral spring 13. The die46 is suitably recessed ad acent the pin 45, which is connected to thedie 12, so that'any rotation thereof 'Wlth respect to the-die 46 isprevented; The die 12 is slot- '-;.tedat the right hand side thereof, sothat 5 when it is lowered,it does not move the dog 14 as issliown inFig. 9, while the die-19 is not slotted so that when it is lowered, 1t

' cooperates with therbeveled top of the 'dog 14 and moves it to theright, thus releasing the die 18 and permitting it to fall to its downmoveinent'at certain times. the pin-7 to shift from the slot 3 to theslot lowermost position. The guide-piece 2 has -.male die 46 issecu-redby means of a suitably slanting slots 3 and 4 having vertical legs 5 and6 out therein. The slide 11 has a pin 7 secured thereto, which has ahead suitably fastened therein by means of a threaded projection 21, andthis fits into the slots of the guide-piece 2, so that as the slide 1 ismoved up and down, together with "the heated by a steamjacket orbyvanyother upwardly by the spring 30with a snap, and the storedenergyof the spring 30 1s sufficient to throw the pin 7 together with thedownward or nextmovement of the head 1, will' cause the slide 11 to movein the opposite direction.

in this manner, as the head.,.1.and .the cross-head 10 are moved up' anddown, the

slide 11 is'alternately placed in cooperative relation with the slots 3and4, sothat the die 18 and stud 53 cooperate alternately with thestud'46 and the;die112, and theipl'unger 40 and the die 19. I

The die-18 and stud 53 ca i be suitably means which are notiillustratedin the drawing as they are inrthemselvess old and-.well

known and form no part of my invention, and are within-the comprehensionof. any person skilled in the art "Suitable regulating means'forthe'heatmay, of course, be employed The 7 surfaces 33 are sufficientlyseparated to prevent any catching of: the bottom'of the yoke'when it isoperated so as toshift'theslide'11.' w

. slide llsufiiciently, so as to causethe pin 7 to cooperate withlthe"slot 3', so that the The operation ;of my'device is asafollows:

The operator sees that-the die 18 and the 'stud53 are suitably heated,and-moves the die-18 to its uppermost position, shown in Fig. 7 andcauses it to engage-in the slot 15 of the'dog 14. He then takes acircular piece of celluloid -48 of: the proper size, shown in Fig-'11,andplaces'it within the 7 die 18, as'shown in'Fig. 7. Thedie18 andcross-head 10, the slide 11 will be shifted from leftto right, or viceversa, and also w1ll be compelled to partake of the up-and- To cause 4,as is shown in Fig. 3, a device is employed which is illustrated clearlyin Figs. 3 to 6, mclu'sive. At the rear ofthe guide-plate 2, a yoke 22having a recess 34, is pivoted at 23.

The bottom 36 of the yoke 22 has beveled faces 35. A spring 30 issecured to the pro ectlon 29 by a sultabl-e screw or the like,

. and the curveof this rests upon the screw 31 ,which may be adjusted soas to cause the spring 30 to upwardly urge the cam head '32 to anydesired extent. The cam head 32 1 has'beveled faces 33 adaptedtocooperate with the beveled faces 35.

When the operator moves the head] 1 to its uppermost posi- 1 tion, thestud 7 is substantially on the central line between the slots 3 and 4. 7'As this is done, one offthe bevel surfaces 35 of the yoke 22;will bear.against the adjacent and -outermost bevel edge of the cam head 32,

and force it downwardly against the resistance of the spring 30. Whenthe yoke 22 is revolved suff ciently so that the other bevel surface35contacts with; the adjacent bevel surface 33, the cam head 32 is forcedthe stud 53 now form what may be termed a composite female die which"cooperates relative movement with respect to the stud 46, as is shownin Fig. 9.

j The operator now upwardly moves the head 1 whereby the yoke 22' andthecam head 32automatically shift the slide 11, so that it willcooperate with the slot 4gof the guide-piece2. While the head '1 is inits uppermost position, the operator places the stiffener 49 on thecelluloid top 52- and; also laces on top of this-a metal base 47}havingthe boss 51, as'is shown in FigfSijThG plunger 40 is pushed within'thedie 19, as it is pressed against themeta'l base '47, as thecross-head 10 again descends, while the die 19,,cooperating with theupper bevel surface of thedog 14, moves the dogato the at the propertime, and causes the die 'the die 19 and plunger 40 act as a compositefemale die. By the action of this second set of dies, the metal 'base 47is forced into the celluloid top 52 whose flanges are crimped thereoverso as to tightly hold it. The recess 50 in the plunger 40 fits on theboss 51, so that when the cross-head 10 is again upwardly moved, theentire completed button is carried along with it to be discharged whenthe bevel surface 42 acts upon the pin 41 and forces the plunger 40 outof the die 19, as is shown in Fig. 7.

I have shown a preferred embodiment of my invention but it is clear thatnumerous changes can be made in its details without departing from theappended claims, and I do not wish to be limited to these details.
